PUMP.

SPECIFICATION forming part of Letters Patent No. 280,402, dated July 3,1883.

Application filed October l1, 1882. (No model.)

To (all whom it may concern:

Be it knownthat I, JOHN B. Roo'r, of Port Chester, in the county ofWestchester and State of New York, have invented a certain new anduseful Improvement in Pumps, that is fully and clearly described bylthefollowing specification, and illustrated in the accompanying drawing.

The object of my invention is the production of a cheap, effective, anddurable handpump; and it consists in certain improvements in the floatand valves of that class of pumps which employ a float or displacerattached to the pump-rod for the purpose of preserving the flow of thewater during the downstroke, and by its buoyancy to eflject or assist ineffecting the upstroke.

'In the drawing accompanying this description the figure is a centrallongitudinal section of a pump embodying my improvements. A is thebarrel of the pump, constructed preferably of sheet metal, and providedwith a shelf, a, for the support of the plug 0, which carries theinduction-valves c,- and B is the float, which in this case is a hollowcylinder constituting the pump-rod, as the pump-handle D and thecollapsing bucket b are attached directly thereto.

Attached to the plug 0 is a rod, F, on which the float slides during itsstrokes. A head on V the upper end of this rod and a bushing in thelower end of the cylindrical chamber B prevent the plunger l'rom risingtoo high when the pump is being operated; and these connections betweenthe float and the valves render access to the valves for the purpose ofremoving clogging material or repairing broken parts an easy matter, asthe float can at any time be lifted entirely out of the pinup-barrel,and with it the plug 0, with the inductionvalves.

G is a head fitted in the end the pumpbarrel, which serves to keeptheibarrel. closed against the upward dash of the water as the floatdescends, and also as a guide and support for the upper end of the floaiwhich always projects beyond this head. i

In the use of such a pump the energy of the workman is applied in themost economical manner and entirely in one direction, it being onlyrequired of him that he throw his weight upon the handle D and depressthe float, for the upstroke may be entirely effected by the buoyancy ofthe float.

Pumps of this class are subjected to the hardest usage and used for agreat variety of purposes, so that great simplicity and strength ofconstruction, together with lightness, are essential considerations.These features of improvement I have secured in my construction bymaking the parts mainly of sheet metal and by so combining the partsthat access can be had to any of them without the necessity of looseningconnections. The most essential feature of improvement, however,consist-s in extending the float beyond the end of the pump-barrel.Ordinarily the bucket and handles and float are attached to a commonrod, or the bucket and handles are attached to the float by separaterods; but by lengthening thefloat as l have described lT am enabled toattach the bucket and handles di rectly thereto and dispense withapu1np-rod,thefloat when thus used being much stronger than a pump-rod,and, having amore extended bearing in the barrelhead, can sustain agreater lateral strain.

Heretofore the float has been inelosed within the pump-barrel, and thebarrel-head had first to be removed before the float could bewit]nlra\\'na necessity and inconvenience not incident to my form ofpump; and, further, the float in my pump cannot be sunk below thesurface of the water, thereby limiting its lilting capacity, as in theold form; but, however dceply it may be depressed, its liftingpower isalways 1'n'oportioned to the depth of its stroke. i

Other forms of buckets maybe used in lieu of the collapsing bucket b,and the connecting-rod F might be rigid with the float and slide throughthe plug (1.

What is claimed as new is 1. The combination, in a pump, of the barrelA, provided with the head G, and a float, B, projecting from thepump-barrel, and provided with the handle D and bucket 6, substantiallyas shown, and for the purpose de scribed.

2. The combination, in a pump, of the barrel A, the float B, projectingfrom the barrel, the plug 0, provided with valves 0, and theconnecting-rod F, substantially as shown, and

for the purpose indicated.
